	/// Example06: The Seesaw
	/// A father of mass m_f and his daughter of 
	/// mass m_d sit on opposite ends of a seesaw at equal 
	/// distances from the pivot at the  center (Fig. 11.9). 
	/// the seesaw is modeled as a rigid rod of mass M and 
	/// length l and is pivoted without friction. At a 
	/// given moment, the combination rotates in a vertical 
	/// plane with an angular speed \omega.
	/// (A) Find an expression for the magnitude of the system's 
	/// angular momentum.
	/// L = l^2/4*(M/3 + m_f + m_d)\omega
	/// (B)Find an expressionfor the magnitude of the angular 
	/// acceleration of the system when the seesaw makes 
	/// an angle \theta with the horizontal.
	/// \alpha = 2(m_f - m_d)g\cos\theta / (l(M/3 + m_f + m_d))
